drivers:misc: ti-st: fix unexpected UART close
Pavan Savoy [Wed, 10 Aug 2011 15:18:37 +0000 (10:18 -0500)]
If suppose the UIM were to die and hence UART were to close when the
Bluetooth/FM or GPS is turned on, prep the ST for a state where-in if
the UIM comes back up, Bluetooth/FM/GPS can be turned on.
